The Grass-Court Championships 2027: Who Wins the Women's Singles?

The grass-court championships in London, the oldest of the four major tennis tournaments, are scheduled from 28 June to 11 July 2027. The defending women's singles champion is Linda Noskova, who beat Karolina Muchova 6-2, 5-7, 6-3 in the 2026 final. The women's event has now had ten different champions in ten editions, and each of the last nine champions was winning it for the first time. Elena Rybakina is world No. 1, with 9,501 ranking points on the official ranking of 26 October 2026. She won two of the four major titles in 2026 and won this event in 2022. The Centre makes her the most likely single player at 16%, followed by Aryna Sabalenka at 12%, Iga Swiatek at 8% and Noskova at 6%. Any other player takes the remaining 58%.

The last player to defend the title was Serena Williams, who won in 2015 and 2016. Since then, every champion has been a first-time winner of this event. Only two of the last six champions were seeded in the top eight.

The format

The women's singles is a 128-player knockout draw played over the two weeks of the championships. With 128 players, a champion must win seven matches (the Centre's own arithmetic). Leading players are seeded, but on grass upsets of top seeds have been common. In 2026 the top two seeds, Sabalenka and Rybakina, lost in the fourth and third rounds. The third seed, Swiatek, also lost in the third round, and the fifth seed, Andreeva, in the second.

The leading contenders

  • Elena Rybakina. World No. 1, nearly 2,000 points clear of the second-ranked player. She won the first and last major titles of 2026, and won this event in 2022. Her record here is 23 wins and 5 losses, including a semi-final in 2024. In 2025 and 2026 she lost in the third round.
  • Aryna Sabalenka. World No. 2. She has reached the semi-finals here three times (2021, 2023 and 2025), with a record of 19-7, but has not reached the final. In 2026, as top seed, she lost in the fourth round.
  • Iga Swiatek. The 2025 champion, who won the final without losing a game. She is ranked No. 8, with a record here of 20-6. As third seed in 2026 she lost in the third round.
  • Linda Noskova. The defending champion, ranked No. 9. She won the 2026 title as ninth seed, her first major title, and has a record here of 11-3.
  • Others. Mirra Andreeva (No. 3, 2026 champion on clay, a quarter-finalist here in 2025), Coco Gauff (No. 5, a 2026 semi-finalist here), Karolina Muchova (No. 7, the 2026 runner-up), Jessica Pegula (No. 4), and every other player in the draw.

Reasoning from the evidence

The Centre weighed four kinds of evidence:

  • Current form and ranking. The official ranking reflects recent results. Rybakina leads it clearly, after two major titles in 2026. Sabalenka is second.
  • Grass record. Rybakina, Swiatek and Noskova have won this event; Sabalenka has three semi-finals. Across the leading players, Rybakina has the best win-loss record here.
  • History of the event. Ten different champions in ten editions, nine first-time champions in a row, and champions seeded 17th, 31st and unseeded within the last six years.
  • The 2026 tournament. The top three seeds all lost by the fourth round, and the final was between the ninth and tenth seeds. That supports a large share for the rest of the field.

The Centre's own calculation from the roll of honour: of the last six champions, two were seeded in the top eight when they won, and four were seeded ninth or lower or were unseeded. No single player has a strong enough case for a weight near one in four. The Centre names four players and gives the rest of the field more than half.

Scenarios: the 2027 women's singles champion

Resolution rule: the forecast resolves on the player officially declared the 2027 women's singles champion of the grass-court championships in London at the end of the final. Later disciplinary or legal decisions are ignored. If the tournament is moved, shortened or played in a different format, the player officially declared champion still counts. If the 2027 tournament is cancelled, or if no women's singles champion has been declared by 31 August 2027, the forecast is withdrawn. The five outcomes are mutually exclusive and cover every possible champion: each of the four named players, or any other player. The weights are whole percentages that sum to 100. If a named player does not enter, withdraws or is eliminated, her weight is not moved to other outcomes; the forecast is scored on the weights as published here. Any later change is issued as a separate dated revision and does not replace this forecast. The cut-off for any dated revision is 23:59 UTC+4 on Sunday 27 June 2027, the day before the first main-draw match on 28 June 2027; no revision is accepted after that. Probabilities are the Centre's analytical estimates. Because the five outcomes have no natural order, the forecast is scored with the multi-category Brier score only; the ranked probability score does not apply.

16%

Elena Rybakina

Rybakina combines the strongest recent results in the women's game, with two major titles in 2026 and the No. 1 ranking, with a title and a 23-5 record on this grass. No other player has both. Her weight stays well below one in four because a champion must win seven matches in a row, because she lost in the third round here in both 2025 and 2026, and because no player has defended or regained this title since 2016.

12%

Aryna Sabalenka

Sabalenka is ranked second and has reached the semi-finals here three times. Her weight is below Rybakina's because she has not yet reached a final here, and because she lost in the fourth round in 2026 as top seed.

8%

Iga Swiatek

Swiatek won this title in 2025 without losing a game in the final and has a 20-6 record here. Her weight reflects her current ranking of No. 8 and a third-round loss as third seed in 2026.

6%

Linda Noskova

Noskova is the defending champion and is ranked No. 9. Her weight is the lowest of the four because 2026 was her first run beyond the fourth round here, and because no champion has defended this title since 2016.

58%

Any other player

This outcome covers every other player in the draw, including Andreeva, Gauff, Muchova and Pegula. No single player in this group has a case strong enough for her own outcome, but together they make this the largest share. Four of the last six champions were seeded ninth or lower or were unseeded, and this outcome allows for a new name again.

What to watch

  1. January to June 2027: the first two major tournaments of 2027 and the official ranking, which guides the seeding.
  2. June 2027: the short grass-court season before the championships, the best guide to form on the surface.
  3. The draw: the seeds and the women's singles draw, published shortly before play begins.
  4. 27 June 2027: the last day for dated revisions (23:59 UTC+4). 28 June: first main-draw matches. 11 July: last scheduled day of the championships.
